Predictors of infection-related rehospitalization in heart failure patients and its impact on long-term survival.

ABSTRACT:

Background

Infection is the most common non-cardiovascular cause of re-hospitalizations for heart failure patients. We therefore investigated the predictors of infection-related re-hospitalization (IRRH) in heart failure patients and its impact on long-term survival.

Methods and results

We prospectively recruited 622 patients after the index hospitalization for decompensated heart fail with primary endpoints of IRRH and all-cause mortality. During follow-up of 3.9?±?2.7 years, IRRHs occurred in 104 (16.7%) patients. Of the 104 patients who experienced IRRHs, the time from the index hospitalization to IRRH was 1.0 (interquartile range: 0.4-2.6) years. Independent predictors of IRRH were age (hazard ratio: 1.02, 95% confidence interval: 1.01-1.04), diabetes mellitus (2.12, 1.42-3.17), not taking angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (1.67, 1.01-2.78), needing maintenance therapy with a loop diuretic (2.10, 1.36-3.26), hemoglobin levels (0.87, 0.79-0.96), and estimated glomerular filtration rates (eGFRs) (0.99, 0.98-0.99). IRRH independently predicted all-cause mortality (1.99, 1.32-2.98) after adjusting for age, body mass index, New York Heart Association functional class, chronic obstructive pulmonary disease, brain natriuretic peptide, hemoglobin, and eGFR. The increased risk of death associated with IRRHs was predominantly for lower respiratory tract infections (3.71, 2.28-6.04), urogenital tract infections (2.83, 1.32-6.10), and sepsis (3.26, 1.20-8.85).

Conclusion

IRRHs in patients discharged for acute decompensated heart fail independently predicted worse long-term survival. We further identified independent predictors of IRRHs. These findings warrant future studies for tackling IRRH.

Project description:AimsThe aim of this study is to determine the impact of diabetes mellitus on all-cause mortality and rehospitalization rates at 3 months and at 1 year in patients admitted with acute heart failure (AHF) stratified by left ventricular ejection fraction (EF).Methods and resultsWe analysed consecutive patients admitted to 47 hospitals in seven Middle Eastern countries (Saudi Arabia, Oman, Yemen, Kuwait, United Arab Emirates, Qatar, and Bahrain) with AHF from February to November 2012 with AHF who were enrolled in Gulf CARE, a multinational registry of patients with heart failure (HF). AHF patients were stratified into three groups: HF patients with reduced (EF) (HFrEF) (<40%), HF with mid-range EF (HFmrEF) (40-49%), and HF patients with preserved EF (HFpEF) (≥50%). Analyses were performed using univariate and multivariate statistical techniques. The mean age of the cohort was 59 ± 15 years (ranging from 18 to 99 years), and 63% (n = 2887) of the patients were males. A total of 2258 (49%) AHF patients had diabetes mellitus. The mean EF was 37 ± 14%. A reduced EF was observed in 2683 patients (59%), whereas 962 patients (21%) had mid-range and 932 patients (20%) had preserved EF. Multivariable analyses demonstrated no significant differences in all-cause mortality between diabetics and non-diabetics in all the three types of HF; at 3 months follow-up: HFrEF [adjusted odds ratio (aOR), 1.30; 95% confidence interval (CI): 0.94-1.80; P = 0.119], HFmrEF (aOR, 0.98; 95% CI: 0.51-1.87; P = 0.952), and HFpEF (aOR, 0.69; 95% CI: 0.38-1.26; P = 0.225); and at 12-months follow-up: HFrEF (aOR, 1.25; 95% CI: 0.97-1.62; P = 0.080), HFmrEF (aOR, 1.07; 95% CI: 0.68-1.68; P = 0.783), and HFpEF (aOR, 1.07; 95% CI: 0.67-1.72; P = 0.779). There were also no significant differences in rehospitalization rates between diabetics and non-diabetics in all the three types of HF; at 3 months follow-up: HFrEF (aOR, 0.94; 95% CI: 0.74-1.19; P = 0.581), HFmrEF (aOR, 0.82; 95% CI: 0.53-1.26; P = 0.369), and HFpEF (aOR, 1.06; 95% CI: 0.64-1.78; P = 0.812); and at 12-months follow-up: HFrEF (aOR, 0.93; 95% CI: 0.73-1.17; P = 0.524), HFmrEF (aOR, 0.81; 95% CI: 0.56-1.17; P = 0.257), and HFpEF (aOR, 1.29; 95% CI: 0.82-2.05; P = 0.271).ConclusionsThere were no significant differences in 3 and 12 months all-cause mortality as well as rehospitalization rates between diabetics and non-diabetic patients in all the three types of AHF patients stratified by left ventricular ejection fraction.
